Earthquakes. +5

Well, I hope you didn't have your finger in there.

im no geoligist, but going to say heat, folding, bending, birthplace of volcanoes.

A mountain range

of course itd be an valcano bc when they colide it builds up heat and it all excapes thru that hold/crack opened and could also send a tital wave(how ever u spell it)

When two continents collide, they produce a massive folded mountain belt like the Himalayas. The collision itself is not likely to cause a tidal wave nor does it cause volcanism. As a matter of fact, this type of collision results in the end of volcanism along a convergent plate boundary.

A mountain ridge.

shattered dishware, ha! ha! mountain ranges and unpredictable interactions between the inner earth and the atmosphere, sometimes resulting in volcanic releases, although usually not. NOW, if one plate 1,000 miles wide crashes into a plate that's 1,500 miles wide, and they overlap 10 miles, what happens in the space (10 miles) from which they moved?

It is called a Convergent Boundary. Usually, one plate will subduct under the other and Orogeny (mountain building) will result on the top plate. However, it is very difficult for continental crust to be subducted so this is not always the case. Sometimes, there is a collision and parts of one plate slide over the other with little to no subduction, making the crust thicker. This type of event has resulted in creating the more spectacular events of Orogeny we have seen in the Earth's history. Currently this type of collision can be seen in the Himalayas, but the Appalachian were a much larger mountain range in their heyday. Starting with the Taconic Orogeny when the Bronson Hill island arc smacked into Laurentia (the ancient continent that makes up most of current day North America). There were then subsequent impacts from other subcontinents. The converging of Avalon with Laurentia, mashing the rest of the Bronson Hill arc completely into Laurentia during the Acadian Orogeny. The Caledonian Orogeny then followed with Baltica (currently the Baltic Shield and makes up Scandinavia) converging into the now Northern side of what was Laurentia. Heavy stuff. Pangaea has since broken up obviously. But, the massive mountain range that once existed can be seen in the Appalachians, the Anti-Atlas range in Africa, the hills of Scotland, and the Scandinavian range. They all used to be one huge range.
